Conversely, you're an American and you want to change this, feel free to propose and pass an amendment that makes regulation of OS as a product the concern of the federal government, as opposed to (as per the 10th Amendment) a state government concern. These regulations are state affairs for the same reason that glyphosate is known in the state of California as a carcinogen (but not other states). Product standards are, generally, a state-level concern. I agree this is inefficient, but the burden to modify the Constitution is on those who would change that inefficiency.
I appreciate the grace in taking a step back on my other comment; I phrased it poorly. Here's my point in better summary: I think we have an issue right now where our hobby has two things that are true that have significant negative societal outcomes. And to be clear, I'm primarily responding to this comment: "Who is providing them with legal indemnification since they are now apparently subject to fines for a fucking hobby if they do it wrong?" Because the answer to that is "If these things are true, it doesn't matter."
1. There is very little daylight between professional and hobby coding. That has been one of its virtues: a person with the right idea can garage-hack way into becoming Fark, or Slashdot, or Craigslist. But the flipside of that coin is that a kid messing around in their garage can cause real consequences for real people they will never even meet. How many websites are falling over from people experimenting with AI crawling right now (at disregard for the existing best-practices for crawling)?
2. A lone actor misusing the machine can have large-impact consequences on strangers. A kid in their basement doing script-kiddie garbage can exfiltrate confidential data, steal someone's electricity to mine Bitcoin, or even just wreck their machine remotely, for fun. A lone actor with no malicious intent but simple negligence can drop a machine on the Internet with all the ports open and become a botnet node. When we have sitautions like that in the past, we often use licensure to ensure some minimum standard of care when using the shared resource.
In fairness, what may want to be licensed here is using the Internet, not installing an operating system. I think that's a fair point and state governments trying to move the issue to the OS, not network-connectivity level, are making a mistake.
